Initial Delivery State

Table 1: Initial delivery state of programmable devices on the module

Boot Process

4 of the 7 boot mode strapping pins (MIO2 ... MIO8) of the Xilinx Zynq-7000 SoC device are hardware programmed on the board, 3 of them are set by the SC CPLD firmware. The boot strapping pins are evaluated by the Zynq device soon after the 'PS_POR' signal is deasserted to begin the boot process (see section "Boot Mode Pin Settings" of Xilinx manual UG585).

The TE0782 board is programmed in the SC CPLD firmware to boot initially from the on-board QSPI Flash memory U38. See section Bootmode in the TE0782 SC CPLD reference Wiki page.

The JTAG interface of the module is provided for storing the data to the QSPI Flash memory through the Zynq-7000 device.

For detailed information about the pin-out, please refer to the Pin-out table.

MGT Lanes

The Xilinx Zynq-7000 SoC used on the TE0782 module has 16 MGT transceiver lanes. All of them are wired directly to B2B connectors J1 and J3. MGT (Multi Gigabit Transceiver) lane consists of one transmit and one receive (TX/RX) differential pairs, four signals total per one MGT lane with data transmission rates up to 12.5Gb/s per lane (Xilinx GTX transceiver). Following table lists lane number, FPGA bank number, transceiver type, signal schematic name, board-to-board pin connection and FPGA pins connection:

Board to

Table 3: MGT lanes

There are 2 clock sources for the GTX transceivers. MGT_CLK1 and MGT_CLK4 are connected directly to B2B connector J3 and J1, so the clock can be provided by the carrier board. Clocks MGT_CLK0, MGT_CLK3, MGT_CLK5 and MGT_CLK6 are provided by the on-board clock generator (U2). As there are no capacitive coupling of the data and clock lines that are connected to the connectors, these may be required on the user’s PCB depending on the application.

Pin Definitions

Pins with names ending with _VRN and _VRP are connected to Zynq PL HP bank special purpose pins VRN/VRP and can be routed to DCI calibration resistors on the baseboard. Otherwise they are usable as general purpose I/Os.

Bank 35 has 100 ohm DCI calibration resistors installed, it is also possible to "borrow" the DCI calibration from bank 35 for banks 34 and 33. For more detailed information about the DCI check Xilinx documentation.

On-board Peripherals

System Controller CPLD

The System Controller CPLD (U14) is provided by Lattice Semiconductor LCMXO2-1200HC (MachXO2 product family). It is the central system management unit with module specific firmware installed to monitor and control various signals of the FPGA, on-board peripherals, I/O interfaces and module as a whole.

See also TE0782 CPLD reference Wiki page.

eMMC Flash Memory

eMMC Flash memory device (U15) is connected to the Zynq PS MIO bank 500 pins MIO10..MIO15. eMMC chips MTFC4GMVEA-4M IT (Flash NAND-IC 2x 16 Gbit) is used with 4 GByte of memory density.

DDR3L Memory

By default TE0782-02 module has two 16-bit wide IM (Intelligent Memory) IM4G16D3FABG-125I DDR3L SDRAM (DDR3-1600 Speedgrade) chips (U10, U19) arranged into 32-bit wide memory bus providing total of 1 GBytes of on-board RAM.

Quad SPI Flash Memory

Two quad SPI compatible serial bus flash memory for FPGA configuration file storage is provided by Spansion S25FL256SAGBHI20 (U38) with 256 Mbit (32 MByte) memory density. After configuration completes the remaining free memory can be used for application data storage. All four SPI data lines are connected to the FPGA allowing x1, x2 or x4 data bus widths to be used. The maximum data transfer rate depends on the bus width and clock frequency.

Gigabit Ethernet PHYs

On-board Gigabit Ethernet PHYs (U18, U20) are provided by Marvell Alaska 88E1512. The Ethernet PHYs' RGMII interfaces are connected to the Zynq's PS MIO bank 501 and to PL bank 9. I/O voltage is fixed at 1.8V for HSTL signaling. The reference clock input of both PHYs is supplied from an on-board 25.000000 MHz oscillator (U11).

High-speed USB ULPI PHYs

Hi-speed USB ULPI PHYs (U4. U8) are provided with USB3320 from Microchip. The ULPI interfaces are connected to the Zynq PS USB0 and USB1 via MIO28..51, bank 501 (see also section USB interface). The I/O voltage is fixed at 1.8V and PHY reference clock input is supplied from the on-board 52.000000 MHz oscillator (U7).

MAC Address EEPROMs

Two Microchip 24AA025E48 serial EEPROMs (U22, U24) contain globally unique 48-bit node address, which are compatible with EUI-48(TM) specification. The devices are organized as two blocks of 128 x 8 Kbit memory. One of the blocks stores the 48-bit node address and is write protected, the other block is available for application use. The MAC address EEPROMS areaccessible over I²C bus (see also section I²C interface).

Configuration EEPROM

The TE0782 board contains one EEPROM (U26) for configuration and general user purposes. The EEPROMs is provided by Microchip 24LC128-I/ST with 128 KBit memory density, the EEPROM is areaccessible over I²C bus (see also section I²C interface).

Programmable Clock Generator

There is a Silicon Labs I²C programmable clock generator Si5338A (U2) chip on-board. It's output frequencies can be programmed using the I²C bus address 0x70 or 0x71. Default address is 0x70, IN4/I2C_LSB pin must be set to high for address 0x71.

A 25.000000 MHz oscillator (U3) is connected to the pin IN3 and is used to generate the output clocks. The output voltage of the oscillator is provided by the 1.8V power rail, thus making output frequency available as soon as 1.8V is present. All 4 of the Si5338 clock outputs are connected to the MGT banks of the Zynq device. It is possible to use the clocks connected to the GTR bank in the user's logic design. This is achieved by instantiating a IBUFDSGTE buffer in the design.

Once running, the frequency and other parameters can be changed by programming the device using the I²C bus connected between the FPGA (master) and clock generator (slave). For this, proper I²C bus logic has to be implemented in FPGA.

 There are 3 LED's on TE0729:

Ethernet

The TE0729 is equipped with a Marvell Alaska 88E1512 Gigabit Ethernet PHY (U3) and has in this TRM the identifier Ethernet0. The Ethernet0 PHY RGMII Interface is connected to the Zynq ETH0 PS GEM0. The I/O Voltage is fixed at 1.8V for HSTL signaling.

SGMII (SFP copper or fiber) can be used directly with the Ethernet PHY, as the SGMII pins are available on the B2B connector J2.

The reference clock input of the PHY is supplied from an on board 25MHz oscillator (U10).

Ethernet0 PHY connection:

Those PHYs can be operated as Ethernet interfaces 10Base-T or 100Base-T with for 4-wires twisted pair cable. The reference clock input of both PHYs is supplied from the same 25MHz oscillator (U10), which also provides Ethernet0 Gigabit PHY with a reference clock signal.

Ethernet1 PHY connection to B2B-connectors:

Ethernet2 PHY connection to B2B-connectors:

All other pins of the PHYs are connected to Bank34 of Zynq, see schematic for further details.

USB

The USB PHY USB3320 from Microchip is used on the TE0729. The ULPI interface is connected to the Zynq PS USB0. The I/O Voltage is fixed at 1.8V.

The reference clock input of the PHY is supplied from an on board 52MHz oscillator (U12).  

PHY connection:

The schematic for the USB connector and required components is different depending on the USB usage. USB standard A or B connectors can be used for Host or Device modes. A Mini USB connector can be used for USB Device mode. A USB Micro connector can be used for Device mode, OTG Mode or Host Mode.
